Two things occur with the key on in your truck-the glow plugs heat if connected and the fuel shut off opens. The injectors are operated with fuel pressure from the injector pump only.

Any idea why I have to use starting fluid every time even after it sets for only 15 or 20 minutes when it does start it runs great

Check the glow plugs. With an ohmmeter, check from the plug tip to ground after it had been sitting overnight. The reading should be somewhere around .2 ohms. Less than that it is probably shorted, more than that it is either going open, or already open.
